Description

We had a document where the fonts were listed in PDFDebugger under Page: 1 / Resources / Fonts, but not found during rendering.

The issue is a malformed Stream in a Form XObject, which is causing an exception that is not intercepted. Then the resources are not restored when the processing of the page continues after that XObject.
